Thyroid uptake measurements are generally used to determine conditions ofhyperthyroidism. High uptake results are found in Graves disease, toxic nodular goiter, TSH-induced, or with stimulator secreting tumors. Low uptake results are found with thyroidhormone secretion in ectopic tumors, hormonal release in thyroid injury, after intake ofthyroid hormone, or Jod-Basedow disease. During the treatment of thyroid cancer by I-131oblation, uptake measurements are used to monitor thyroid activity.The CAPTUS® 2000 system will store patient demographic and dosage information, countdata for both the administered dosage and the patient, decay correct all count data, calculatethyroid uptake results, and store all of this information in the thyroid uptake library.
